High-throughput mass spectrometry-based proteomics is gaining increasing interest, but mass spectrometers need to adapt to enable faster analysis times. For Orbitrap mass spectrometers, faster scan rates are constrained by limitations on ion accumulation time, duty cycle, and transient length. Here, we introduce a new scanning strategy called "pre-accumulation" that enables storing ions in the bent flatapole in parallel with the C-trap/IRM operation. This significantly improves ion beam utilization and allows scanning speeds over 70 Hz on hybrid Orbitrap instruments.The combination of pre-accumulation and increased scan speeds enhances peptide and protein group identifications for short LC gradients, and improves sensitivity for high-throughput applications. These benefits are further amplified when coupled with full mass range phase-constrained spectrum deconvolution (ΦSDM), especially for fast, lower-resolving Orbitrap measurements. The pre-accumulation approach offers distinct advantages, particularly for conditions with reduced signal input, and does not require any hardware changes, making it highly attractive for Orbitrap mass spectrometers used with fast MS/MS acquisition methods.
